How safe is it to unlock 6950x2?

post #1 of 12
Thread Starter 
I was about to replace my 5970 for two 6970's, but then I realized I could just unlock 6950s to 6970 clocks and voltages. My question is out of ten the probability of this being sucessfull....

Also what is the best brand for reference 6950/6970s?

5970 to 6950 - why? I mean even 2 won't give you much of a performance increase. 5970 costs 100 dollars more than 2 6950s here lol. But should be quite safe, but I must admit I doubt that you'll be able to overclock them really much.

It will still give me a significant performance increase. I plan on doing Eyefinity soon and the 4GB opposed to the 2GB will really help. Also I am getting similar, if not better performance, while receiving 100 bucks. I see that as a great opportunity to be taken...

i went from 5970 to 6950 crossfire and you will see a massive improvement in minimum frame rates and also everything is much smoother. Well worth upgrade IMO

Maybe should google around a bit instead of guessing. They overclock fine. The wall seems to be around 925/1425 ish for a lot of folks. Your chances of failing to inlock are the same chances of you screwing it up by unlocking the shaders or overclocking it yourself; essentially there's no risk. Worst case you RMA then flash the new one =)

You do realize you will only get an effective 2GB on the two 6950 crossfire. Memory does not add up in crossfire. But if you can break even or sell the 5970 for a profit, then by all means go for it.

^^ Crap I forgot about dat! The card with the lowest amount of memory, is the memory you end up with XD.
